4. [+40, -0] Backstroke position is dangerous for them. Grampuses are cruel, smart, and live in a group. They could've killed the humpback whale by pressing it into the water and drowning it. If the grampuses took turns and did that, the humpback would've drowned to death and became their food... Blue whales are the biggest but grampuses can hunt them with that method. If the picture is true, then the humpback risked their life to save the seal.

6. [+32, -0] Are they clapping to compliment the scuba diver? ㅋㅋㅋㅋ

7. [+29, -0] Humpback whales also sing. Below 15M in the water, they sing. The sound is amazingly big so if you're nearby, your entire body will hurt. Their vocal range is extremely flexible, they can sing very high notes and very low notes. Humpbacks' songs are very complicated. They're said to like learning new songs ㅋㅋ

8. [+28, -0] Humans are the biggest idiots. Animals help each other but humans are busy to backstab each other.
